I donât like the look of my pterygium. If there is no recurrence, it is highly likely that within 6 months after the surgery, you will probably not be able to tell which eye has had surgery.
A methyl group is an alkyl derived from methane, containing one carbon atom bonded to three hydrogen atoms â CH 3. The group is often abbreviated Me.Such hydrocarbon groups occur in many organic compounds. It is a very stable group in most molecules. methyl group is an alkyl derived from methane, containing one carbon atom bonded to three hydrogen atoms â CH 3. The group is often abbreviated Me.
Carboxylic Acids. The carboxyl functional group that characterizes the carboxylic acids is unusual in that it is composed of two functional groups described earlier in this text. As may be seen in the formula on the right, the carboxyl group is made up of a hydroxyl group bonded to a carbonyl group. It is often written in condensed form as âCO 2 H or âCOOH. Other combinations of functional groups were described previously, and significant changes in chemical behavior as a result of group interactions were described (e.g. phenol & aniline).
